How can I determine which
lens version will work best for my
application?

There are three variables that need to be known in order to determine
the most appropriate lens for an application:

The distance from the camera to the object being imaged.
This is usually expressed in feet or meters.

The size of the object being imaged. This is usually the
largest dimension, also in feet or meters, as long as the same units
are used.

The number of pixels that the object needs to cover in the
image, usually using the larger of the horizontal or vertical dimension.

Using these variables, it is possible to calculate the optimal
lens,
since the sensor resolutions and pixels sizes of Boson, Quark2, Tau2,
and legacy Photon cameras are known values. Note that these
calculations become less accurate at very close ranges, or for very
wide field of view lenses.

A simple calculator to help with lens selection for Tau2 and
Quark2 can
be found here.
